Definitions

  • Embodiments of the present invention relate to a cable sealing device for sealing a cable passing through a first and second surface.
  • the criteria of sealing that cable in relation to said two surfaces naturally differ depending of the environmental circumstances. If the surfaces are part of an arrangement handling an inflammable substance, such as a fuel dispensing unit, the criteria of the sealing is high.
  • Fuel dispensing units generally comprise electronics in order for the user to be able to control the hydraulics of the fuel dispensing unit and refuel e.g. a vehicle.
  • the electronics of the fuel dispensing unit can provide an increased risk in that for instance sparks from electronic circuitry and/or heat radiated from the electronic wiring and circuitry could ignite the fuel vapors.
  • the hydraulics and the electronics of a fuel dispensing unit are located in separate compartments or modules.
  • Embodiments of the present invention provide an improvement of the above technique and prior art. More particularly, an embodiment of the present invention provides an improved cable sealing device containing a decreased amount of parts and contributing to a simplified mounting of the same. Further, an embodiment of the present invention provides an electronics module for a fuel dispensing unit, a fuel dispensing unit and a method for sealing an opening in a first surface and an opening in a second surface.
  • a cable sealing device for sealing a cable passing through a first and second surface according to embodiments of the present invention.
  • a cable sealing device for sealing a cable passing through a first and second surface.
  • the cable sealing device comprises a first sealing element extending in a first radial direction of the cable and configured to surround at least a portion of the cable and to seal an opening in the first surface, and a second sealing element extending in a second radial direction of the cable and configured to surround at least a portion of the cable and to seal an opening in the second surface.
  • the extension of the first sealing element in the first radial direction is smaller than the extension of the second sealing element in the second radial direction.
  • the cable sealing device may be provided on the cable before it is passed through the surfaces to be sealed.
  • the cable is automatically sealed when the first and second sealing element reaches the first and second surface, thereby simplifying the mounting to a great extent. In view of the above, the costs for manufacturing and mounting of the cable sealing device are decreased.
  • the first sealing element and second sealing element may be integrally formed, which is advantageous in that is decreases the amount of parts even further.
  • the extension of the first sealing element and the second sealing element may have the same length in all radial directions of the cable, thereby centering the cable in each sealing element.
  • the length of the extension of the first sealing element and the length of the extension of the second sealing element differ due to different radii of the two sealing elements.
  • the cable sealing device may be attached to the cable to be sealed, which is advantageous in that the cable can be manufactured and distributed already provided with the cable sealing device. The mounting of the cable and the cable sealing device is thus further facilitated.
  • the second sealing element may have a flange adapted to fit into a corresponding recess of the opening to be sealed for retaining the second sealing element at said opening, which is advantageous in that a tight sealing will be ensured. Also, this way the amount of parts of the cable sealing device is kept down since no further locking device for the second sealing device will be needed.
  • the cable sealing device may further comprise a locking device for locking the first sealing element in the opening to be sealed, which is advantageous in that a tight sealing will be ensured.
  • the first sealing element and said second sealing element each may comprise a gasket for tight sealing against the openings to be sealed, which is advantageous in that a tight sealing will be ensured.
  • the first sealing element and the second sealing element may be spaced apart such that a space may be allowed between the first and second surface when the first sealing element seals the opening in the first surface and the second sealing element seals the opening in the second surface.
  • an electronics module for a fuel dispensing unit comprising a first compartment having a first opening, a second compartment having a second opening, a cable extending between the first and the second compartment through the first and the second opening, a cable sealing device configured to seal the first opening in the first surface and the second opening in the second surface.
  • the cable sealing device comprises: a first sealing element extending in a first radial direction of the cable and configured to surround at least a portion of the cable and to seal an opening in the first surface; and a second sealing element extending in a second radial direction of the cable and configured to surround at least a portion of the cable and to seal an opening in the second surface, wherein the extension of the first sealing element in the first radial direction is smaller than the extension of the second sealing element in the second radial direction.
  • a fuel dispensing unit for refueling motor vehicles comprises a cable sealing device comprising: a first sealing element extending in a first radial direction of the cable and configured to surround at least a portion of the cable and to seal an opening in the first surface; and a second sealing element extending in a second radial direction of the cable and configured to surround at least a portion of the cable and to seal an opening in the second surface, wherein the extension of the first sealing element in the first radial direction is smaller than the extension of the second sealing element in the second radial direction.
  • the invention relates to a method for sealing an opening in a first surface and an opening in a second surface.
  • the method comprises providing a cable with a sealing device comprising: a first sealing element extending in a first radial direction of the cable and configured to surround at least a portion of the cable and to seal an opening in the first surface; and a second sealing element extending in a second radial direction of the cable and configured to surround at least a portion of the cable and to seal an opening in the second surface, wherein the extension of the first sealing element in the first radial direction is smaller than the extension of the second sealing element in the second radial direction; and wherein the first sealing element seals the opening in the first surface and the second sealing element seals the opening in the second surface.
  • a fuel dispensing unit for refueling motor vehicles comprises an electronics module comprising: a first compartment having a first opening in a first surface; a second compartment having a second opening in a second surface; a cable extending between the first and the second compartment through the first and second opening; and a cable sealing device.
  • the cable sealing device comprising: a first sealing element extending in a first radial direction of the cable and configured to surround at least a portion of the cable and to seal an opening in the first surface; and a second sealing element extending in a second radial direction of the cable and configured to surround at least a portion of the cable and to seal an opening in the second surface, wherein the extension of the first sealing element in the first radial direction is smaller than the extension of the second sealing element in the second radial direction.
  • FIG. 1 is a perspective view of a cable sealing device according to an aspect of the invention when unassembled
  • FIG. 2 is a perspective view of the cable sealing device when assembled and sealing against a first and a second surface
  • FIG. 3 is a perspective view of a fuel dispensing unit comprising an electronics module having a plurality of cable sealing devices.
  • FIG. 1 illustrates a cable sealing device 1 according to one embodiment of the present invention when unassembled.
  • the cable sealing device 1 is adapted to seal a cable 2 passing through a first surface 3 and a second surface 4 , preferably in an electronics module of a fuel dispensing unit.
  • the cable sealing device 1 has a first sealing element 5 extending in a first radial direction R 1 of the cable 2 surrounding the cable 2 , and is adapted to seal an opening 6 in the first surface 3 .
  • the cable sealing device 1 further has a second sealing element 7 extending in a second radial direction R 2 of the cable 2 surrounding the cable 2 , and is adapted to seal an opening 8 in the second surface 4 .
  • the first 5 and second 7 sealing elements need not entirely surround the cable 2 . That is, depending on specific sealing requirements the sealing elements 5 , 7 may partially surround the cable so as to allow openings in the sealing elements 5 , 7 .
  • This alternative embodiment may be advantageous when a less strict sealing is called for, e.g. when sealing different portions of the electronics module, wherein the openings in the sealing elements may comprise dust filters allowing air, but not dust, to flow between different portions of the electronics module.
  • the extension E 1 of the first sealing element 5 in the first radial direction R 1 is smaller than the extension E 2 of the second sealing element 7 in the second radial direction R 2 .
  • the first sealing element 5 is preferably integrally formed and the extension E 1 preferably has the same length in all radial directions of the cable 2 .
  • the second sealing element 7 is preferably also integrally formed and the extension E 2 preferably has the same length in all radial directions of the cable 2 .
  • the cable sealing device 1 is attached to the cable 2 to be sealed upon delivery. That is to say, when the cable 2 is distributed, it is already provided with the cable sealing device 1 .
  • the second sealing element 7 has two flanges 9 adapted to fit into corresponding recesses 10 of the opening 8 to be sealed for retaining the second sealing element 7 at the opening 8 .
  • the two flanges 9 are guided through the corresponding recesses 10 , after which the second sealing element 7 is rotated in relation to the second surface 4 , such that the second sealing element 7 is locked against the second surface 4 .
  • the cable sealing device 1 has a locking device 11 for locking the first sealing element 5 in the opening 6 to be sealed.
  • the locking device 11 has two flanges adapted to fit into corresponding recesses provided in the first sealing element 5 for retaining the first sealing element 5 at the opening 6 .
  • the two flanges of the locking device are guided through the corresponding recesses of the first sealing element 5 , after which the locking device 11 is rotated in relation to the first sealing element 5 , such that the first sealing element 5 is locked against the second surface 4 by means of the locking device 11 .
  • the first sealing element 5 and the second sealing element 7 each comprises a gasket 12 , 13 for tight sealing against the openings 6 , 8 to be sealed in the first and second surface 3 , 4 .
  • the first sealing element 5 and the second sealing element 7 are spaced apart such that a space S is allowed between the first and second surface 3 , 4 when the first sealing element 5 seals the opening 6 in the first surface 3 and the second sealing element 7 seals the opening 8 in the second surface 4 .
  • the cable sealing device 1 is illustrated when assembled.
  • the gasket 12 of the first sealing member 5 abuts against the underside of the first surface 3 and the locking device 11 abuts against the upper side of the first surface 3 , thereby sealing the opening 6 .
  • the gasket 13 of the second sealing member 7 abuts against the underside of the second surface 4 and the flanges 9 abuts against the upper side of the second surface 4 , thereby sealing the opening 8 .
  • FIG. 3 illustrates an electronics module 14 provided in a fuel dispensing unit 15 .
  • the electronics module 14 has a first compartment 16 having a plurality of first openings 6 in the first surface 3 , and a second compartment 17 having a plurality of second openings 8 in the second surface 4 .
  • Each first and second opening 6 , 8 is sealed by means of a cable sealing device 1 attached to each cable 2 extending between the first and the second compartment 16 , 17 through said first and second opening 6 , 8 .
  • the need for proper sealing depends on the environmental circumstances. If a cable for example is to be pulled from the hydraulics compartment up and into the electronics compartment of a fuel dispensing unit, there is a risk of bringing inflammable substances into the electronics compartment and thus increasing the risk of explosion. Accordingly, the requirements regarding that type of sealing are high. The requirements may be lowered by letting the cable extend through an air gap between the compartments through which it is drawn. That is to say, it is preferred if the cable extend from a first compartment, i.e. the hydraulics compartment of a fuel dispensing unit, through an air gap where the cable is subjected to ventilation by air and up and into a second compartment, i.e.
  • the cable sealing device is attached to the cable before being assembled.
  • the cable carrying the cable sealing device is drawn from a first opening in a first surface in a first compartment up and into a second opening in a second surface in a second compartment.
  • the first sealing element of the cable sealing device will seal the first opening in the first surface and the second sealing element will seal the second opening in the second surface, and at the same time create an air gap for the cable between the two compartments.
  • the first sealing device is tightly locked against the first opening by means of a locking device.
  • the second sealing device is tightly locked against the second opening by means of two flanges passed through a corresponding recess of the opening.
  • an electronics module for a fuel dispensing unit comprising a cable sealing device according to the features above.
  • a fuel dispensing unit for refueling motor vehicles comprising an electronics module according to the feature above.
  • a method for sealing an opening in a first surface and an opening in a second surface is provided.
  • the cable sealing device is constituted by a small number of parts and the mounting of the same is simplified in relation to prior art. Since the extension of the first sealing element in the first radial direction is smaller than the extension of the second sealing element in the second radial direction, the cable sealing device may be provided on the cable before it is passed through the surfaces to be sealed. Thus, the cable is automatically sealed when the first and second sealing element reaches the first and second surface, thereby simplifying the mounting to a great extent. In view of the above, the costs for manufacturing and mounting of the cable sealing device are decreased.
  • the first sealing element and second sealing element may be integrally formed, which may decrease the amount of parts even further.
  • the extension of the first sealing element and the second sealing element may have the same length in all radial directions of the cable, thereby centering the cable in each sealing element.
  • the length of the extension of the first sealing element and the length of the extension of the second sealing element differ due to different radii of the two sealing elements.
